The role of community health workers in re-entry of people with HIV and substance use disorder released from jail: a mixed methods evaluation of a pilot study.

Abstract

Background: Incarcerated individuals face high rates of mental illness, substance use disorders and communicable diseases including HIV, with increased health complications and mortality in the early post-release period. Multiple re-entry interventions linking justice-involved individuals to community resources via peer navigation have emerged, though limited data exist on the mechanics and personal impact of these approaches. This paper quantifies and evaluates a pilot study of a combined Community Health Worker (CHW)-re-entry intervention for individuals released from jail who use substances and have HIV to inform future large-scale applications.

Methods: A mixed-methods analysis of a CHW-re-entry intervention utilized in a pilot randomized controlled trial involving people with HIV who have a history of substance (stimulant, opioid or alcohol) use in Dallas, TX was conducted using an explanatory sequential design. Quantitative assessments of the intervention measured interaction types, time spent, and topics discussed and explored associations between the "dose" of intervention and patient outcomes. Qualitative analyses of CHW field notes and end-of-study participant interviews were triangulated with quantitative findings to elucidate the intervention's impact.

Results: Of the 17/31 participants assigned to the intervention, 16 interacted with the CHW on at least one occasion, and 6 successfully completed a visit with the re-entry organization. Most CHW interactions occurred by phone (66%) or in person (28%). Frequently discussed topics included substance use, housing, and physical health. On average, participants spent 7.65 h (range 0-37.18, SD = 9.33) engaged with the intervention over 6 months. Intervention dose was associated with improved HIV control, decreased stimulant use, higher rates of recidivism, and improved clinical appointment show rate. Qualitative analyses revealed key intervention components, paralleling benefits of study participation alone: outreach, nonjudgmental approach, motivation and accountability.

Conclusions: A CHW-re-entry intervention, while resource-intensive, shows preliminary promise in improving HIV and some substance use outcomes. Frequent telephone and in-person contact, with an empathetic yet goal-oriented approach, fostered participant support and motivation to address HIV and substance use. Participants reported that engagement in research provided accountability and a sense of purpose. Future studies should focus on optimizing implementation of CHW-based interventions to enhance impact on vulnerable populations.
